I thought the other reason was to help keep the powder from melting the lead thus making your barrel dirty and also changing the weight of the projectile. But, instead of using gas checks, why don't you use a copper jacketed round??? They might be easier to locate and purchase. Don't look for Sierra (my favorite) they haven't made anything in the 44 cal range in about 2 years. Right now I'm using Hornady (I hate them) but their jacket is too thin and not bonded to the lead.
Those are my opinions, other's may vary.

We had a thread that touched on the lead-versus-jacketed just a short while back. I gathered from that:
Never heard of a DW barrel being wore out
even if you did they are easy to change and not overly expensive
the barrels that DID wear out were probably Smiths.. not Dans
I have heard of gas checks (along with high vel/pressure rounds) causing damage to the frame ( I forget the term) but again it was smiths not Dans.
All that said I gennerally shoot plain ole lead.

I have shot gas checked lead for many many years with no ill effects that I know of. I always have been lead to believe the GC was to help prevent leading at higher velocities as well as produce a better bullet to barrel seal , I forget the fancy term for that. I can't prove any of that but they have always worked good for me.
P.S. Maybe eventually Steve's Reloading Roundtable series will get around to casting bullets and such.

One of the things I'm encountering in the accumulation of componants for handloading is that 310 grain bullet are pretty uncommon. I found what looks like a good one on this page
http://www.laser-cast.com/trueshot.html
but it has a gas check. The load data doesn't mention gas checks. Should I not use this bullet?

I run gas checks on everything I load for, except .41 and that's because I haven't found the mold I want and am presently using a really cheap Lee mold, the only thing I've noticed is that when running HOT loads the pressure tops out just a little bit sooner. Pending powder approximately .5 gr. other than that if you're even a little sensible with your loading you should have no problem runnign that bullet. I have a friend who runs LaserCast and he says they're awesome bullets I know they shoot well enough to hit the metal plate @ 150 yds with the Max as long as he does his part. Gas checks are mainly there to keep the hot gasses from being in direct contact with the bottom of the bullet and in so doing they help decrease leading when running hunting type loads, if you're not running a warmer load they are not needed or required as long as the lead is of decent chemical makeup. They do also help seal the bullet better going down the barrel. I'd run it w/o even thinking about it if I was looking for cast bullets in that weight however being a 310 gr. it seems a little useless to have the gas check in a .44 if you ask me. 444 and hot 445 loads now that's a different story then the gas check would be helping you.
